Applications:


HPLC Separation of Methylphosphonic Acid and Related Products


Alkylphosphonic acids are decomposition byproducts of chemical warfare agents. Analysis of phosphonic acid in water is regulated by Environmental Protection Agency (EPA). All phosphonic acids are polar acidic compounds. Analysis for retention and separation of methylphosphonic, ethylphosphonic, ethyl methylphosphonic and isopropyl methylphosphonic acids was developed using Primesep SB reversed-phase anion-exchange column. Method is compatible with LC/MS and can be used for quantitation of phosphonic acid in water.



Application Analytes:

Ethyl Methylphosphonic Acid
Ethylphosphonic Acid
Isopropyl Methylphosphonic Acid
Methylphosphonic Acid

Effect of pH on Separation of Glyphosate and Ethylphosphonic Acid

Glyphosate is broad spectrum herbicide to kill weeds. Presence of glyphosate in water, fruits and veggies is regulated. Alkylphosphonic acids are decomposition byproducts of chemical warfare agents. Analysis of phosphonic acid in water is regulated by Environmental Protection Agency (EPA). All phosphonic acids are polar acidic compounds. Method was developed for glyphosate and ethylphosphonic acid. Both compounds are retained by ion-exchange mechanism. Method is compatible with LC/MS and can be used for analysis of glyphosate and alkylphosphonic acids in various matrices.



Application Analytes:

Ethylphosphonic Acid
Glyphosate
